17edo and 19edo are the smallest edos that offer a greater variety of pitches than 12edo.

Most of the soft step ratio range (1:1 to 2:1) correspond to meantone temperaments. More specifically, the hyposoft range (3:2 to 2:1) corresponds to meantone and the parasoft range (4:3 and 3:2) corresponds to flattone. | |||

===Hyposoft=== | Both meantone and flattone are characterized with flattening the perfect 5th (3/2) to achieve major 3rds that are close to 5/4 (386¢), where the latter has major 3rds that are flatter than 5/4. | ||

The range of hypohard | The range of hypohard step ratios can be divided into a minihard range (between 2:1 to 5:2) and quasihard range (between 5:2 to 3:1). | ||
==== Minihard ==== | ==== Minihard step ratios ==== | ||
Minihard | Minihard step ratios correspond to Pythagorean tuning and schismatic temperament, characterized by having a perfect 5th that is as close to just (701.96¢) as possible, resulting in 81/64 (407.8¢) for its major 3rd. | ||

==== Quasihard ==== | ==== Quasihard step ratios ==== | ||
Quasihard | Quasihard step ratios correspond to "neogothic" or "parapyth" systems whose perfect 5th is sharper than just, resulting in major 3rds that are sharper than 81/64. | ||
17edo is considered to be on the sharper end of the neogothic spectrum, with a major 3rd that is more discordant than flatter neogothic tunings. | 17edo is considered to be on the sharper end of the neogothic spectrum, with a major 3rd that is more discordant than flatter neogothic tunings. | ||
